Abstract
Nitric oxide (NO) is known, since the past few years, as a bioactive molecule playing important role in a number of diverse activities of animals and plants. It is a small, highly diffusible molecule. It can rapidly pass through biological membranes thereby triggering various processes. The regulatory role of NO in plant development and plant interactions with microorganism, involving an interplay with other molecules like ethylene or reactive oxygen species (ROS), is discussed. It is implied to be as an important defence molecule against stress and ROS, however further research is needed to understand conclusive physiological mechanism involved.

Key words: Development, Nitric oxide, Plant growth, Stress tolerance.
